thats wrong dude. I have had the Vortech and you wait for the boost. I have a turbo car and the boost is there before 3k rpm. I shift out much earlier on my mazda than I used to do on my SVT. I would rather make the power down low and save the engine from the abusive high rpms that a centrifigal supercharger requires to make power. I sold my vortech kit to get a turbo for the svt and I wouldn't have went through the hassle if it wasn't worth it. And also, Vortech may have upgraded the jack shaft on the Focus kit but they never did the same to the Contour kit. Oh and hate to burst your bubble but a Vortech blows off too. Only the Vortech uses a recurculating bypass valve. Even worse than a loud blowoff valve because its recirculating hot air as opposed to blowing it off to the atmosphere.
Turbos make tourqe and tourqe makes smiles.
